A CORPORATION OF OHIO ACHINE roa DEEQRMING PIPES Application filed February 11, 1928. Serial No. 253,590.

annular V-shaped groove or-bea'd which islater further deformed by the action of the coupling itself. It is this initial breaking down of thetubethat enables the coupling to further deform the pipe end in the assembling of the'parts of the coupling.

In carrying'out my idea of providing a machine for breaking down the metal of a tube adjacent to an end thereof in order to provide an annular groove, I employ two main drive wheels properlypositioned with respect to one another and having'V-shaped grooves in their peripheries.

above and between the two drive wheels aforesaid, and is adjustable -with' respect rior cylindrical surface of a tube or pipe to deform the same. I

A particularly noteworthy feature of this invention is the adaptability of the machine to function in substantially two different ways in its operation of deforming tube ends. Appropriate clamping means are provided which may be availed of, on the appropriate occasion, to rigidly clamp themachine to any convenient working table orlike article, and a tube is placed in position where it is operated on by the driving and deforming wheels aforesaid, the gears being rotated to cause rotation of the driving wheels. However, should it be desired to deform the end of a pipe already installed or in some. position where it may not be brought to the machine, the clamping means may be dispensed with A comparaf tively small deformingwheel is positioned and a detachable operating member in the form of a crank handle is changed from one mounting in the machine to another. After proper positioning with respect to the tube end, the 'whole machine may be rotated around the pipe as a pivot to cause deformation of thelatter, in the manner intended, the operating member that adjusts the deforming wheel functioning in the same manner as in the previous case.

Still anotherobject of the invention is to provide in a machine of the character referred to, meansfor indicating when a tube has been deformed to an extent previously determined upon. In carrying this thought out into practical operation, I employscrew means for adjusting the deforming wheel, and which screw means may haveassociated therewith an arrow or point that cooperates with suitable indicia to indicate the relation of the deforming wheel with respect to the main drive, and supporting wheels. i

Further more detailed objects andadvantages will in part become'apparent and in part be hereinafter stated such as the particular mounting of the adjusting means for the deforming wheel.

For a full and more complete understanding of theinvention, reference may be had to the following description and accompanying drawings,in whichj Figure l is a view in sideelevation of a machine provided by this invention that is adapted to function while being clamped to a suitable support. 1 i I Figure 2 is a front view ofthe machine shown in Figure 1 that is now adapted for use without the clamping means, with the operating handle in a different position, that will cause rotation of the whole machine around a pipe as a pivot. r I I Figure .3 is a detail view in elevation of one of the parts of the mechanism used in adjusting the deforming wheel.

While a preferred embodiment of the invention is herein set forth, it is to be understood that I am not to be limited to the exact construction as herein described, because various modifications of these details may be provided in putting the invention into practice within the purview of the appended claims. i

A machine made in accordance with this invention comprises a main body portion or casting A which carries the various instrumentalitiescomprising the completely operative machine. The lower end of the casting A terminates in a screw threaded stem 1 that is adapted for insertion in a clamp 2that is availed of when the machine is to be mounted on a Work bench or similar article. The main casting A has upstanding ears 3 at the front thereof that constitute a journal or bearing for certain instrumentalities to be later described, and extending from each side are lugs 4 that provide journals in substantial alignment with the bores in the ears 3. The main casting A above the lugs 4 is of a hollow construction and has front and rear flat faces'5 and 6 that are slotted at 7 and 8. Extending in substantially the same lane with the lugs 4 is a projection 9 havmg an opening extending therethrough at 10 to providea mounting for a handle crank.

which is held in the openingby a set screw 11. Guiding flanges 12 are integral with the main casting A and extend sidewise above the lugs 4 at the front face 50f the main body.

The upper portion of the main casting is exteriorly screw threaded at 13 and when the machine is completely assembled, a cap 14 is threaded thereon. The upper face of this cap may be provided with suitable indicia to cooperate with'apoint indicator to determine the position-of the deforming wheel in a manner to be later described. A carrier member 15 is mounted for longitudinal move- 16. An opening 17 extends transversely across the carrier member 15 and carries a pivot member in a manner to be later set forth. The carrier member 15 may be provided with a guiding projection 18 at the of for the purpose of rotating the member 20. A flange 24 on the member is clamped on the upper end of the main casting A by the cap 13 in a position permitting of rotation of the member 20. A ring 25 having an arrow point 26 may be adjustably affixed to the member 20 through the medium of a set screw 27. The transverse opening 17 in the carrier member 15 is lined with abearing sleeve 28 that functions as a journal for pivot member-.29. Member 29 carries adjacent to its outer extremity. a deforming wheel '30 of appropriate V-shaped configuration. The pivot 29 also has a positioning flange 31 that normally bears against one end of the journal sleeve28. Pivot member29 is held in the journal sleeve 28 by screw 32, the head of which bears against the other end of the said sleeve. It will be apparent from Figures 2 and 8 that the pivot members 29, the extremity of which projects into the slots 7 and .8, are adapted for longitudinal movement therein because of their mounting in the movable carrier member 15. The assemblage just described may be operated by proper rotation of the handle bar 23 to cause longitudinal movement of the deforming wheel with respect to the casting A. I 7 Main driving shafts 33 are journaled in the openings 34 in the lugs 4 and have their extremities at one end appropriately mounted in the ears 3 as shown at 35. Between the lugs 4 and the ears 3 the shafts 33 carry drive wheels 36. These drive Wheels are provided with V-shaped grooves 37 and peripheral driving surfaces 38 that are notched or toothed to provide an engaging surface with the end of the tube operated on by the machine. Spacing washers 39 hold the drive wheels. 36 in a position removed from the main casting A.

The shafts 33 extend through the lugs 4 and at their free ends carry driving gears 40 that are spaced from the main casting by spacing washers 42. Driving gears 40 are in engagement with a main driving gear 43 preferably integral with a pivot member 44 that has appropriate bearing in the main casting A. Main drivinggear 43 may be operated through the medium of a crank handle 45 that is inserted in the opening 46 in the shaft forming a part of the gear, and is held therein by a set screw 47.

As previously mentioned, the machine is adapted for functioning in substantially two distinct ways. When it is clamped to a suitable stationary object by means of the clamp 2, the crank handle 45 is positioned in the opening 46 in the main driving gear and may be operated to cause rotation of the drive wheels 86. A pipe is positioned with respect to the machine so that the end thereof will abut against the positioning flanges 12 while it rests on the main driving wheels 36 and lies therebetween. In this position the deforming wheel 30 will be located interiorly of the tube. The handle bar 23 may now be availed of to operate the carrier 15 to move the deforming wheel down against the interior cylindrical surface of the tubular mem ber operated on by the machine. The forming wheel is forced down tight against the wall of the pipe and the main driving wheel is rotated a few turns after which the deforming wheel 30 is again forced down against the metal of the tube, forcing, the

same into the V-shaped grooves 3'4". In this manner the metal of the tube is broken down to provide a substantially V-shaped annular bead circumferentially thereof.

When a pipe is installed, or for any other reason, cannot be properly positioned with respect to the machine when the same is aflixed to a stationary object, the clamp '2 is dispensed withand the crank handle 45 inserted in the opening at 10. The tube end is then positioned in the usual manner with respect to the machine except that the machine is the movable part and the tube the stationary one, while formerly, the converse of this condition was true. The crank handle 45 may then be employed to rotate the whole machine around the tube end as a pivot. During the normal operation of the machine, it will take several tightenings of' the deforming wheel against the metal by the handle bar 23 to properly break down the metal. of the tube, and the pointer 26, in conjunction with the indicia on the cap member 14, may be availed of to indicatewhen the metal has been sufliciently deformed.

A gear housing 48 encloses the driving gears 40 and main gear 43, the gears being held in place by a retainer 49 having arms 50 extending into notch 51 in the cylindrical surface of the main driving gear 43. The retainer is affixed to the gear housing by a set screw as shown at 52, the housing being made fast to the main casting A.

Having thus described my invention, what Iclaim as new and desire to secure by Letters Patent in the United States, is

1. A pipe deforming machine of the class described, comprising, in combination, pipe deforming instrumentalities, meansfor including an operating member in the machine to operate the deforming instrumentalities, and means permitting of the rotation of the whole machine to perform the deforming functions when the operating member is not included in the machine.

2. In a pipe machine of the class described, the combination with a main body portion, of pipe deforming instrumentalities including gear mechanisms, of means cooperating with the gear mechanisms, comprising a handle receiving member, and a second handle receiving member on the main body, the machine being adapted to function either through the operation of the gear mechanisms or by the rotation of the machine as a whole around the pipe around which the machine is operated. V
